Perform in-place upgrade
Perform an in-place upgrade of the existing HDP 2.6.5.x cluster.
Cloudera recommends that you deploy the HDP intermediate bits in production by performing an in-place upgrade of your existing HDP 2.6.5.x cluster. Contact the Cloudera account team to participate in the Limited Upgrade program. For in-place upgrades, Cloudera works with you to ensure your cluster is ready and meets all the criteria to be successful. As part of the planning exercise to upgrade to the HDP intermediate bits, see the Cloudera Support Matrix to ensure that the Cloudera products you are currently using are certified to work with the HDP intermediate bits. Also, ensure that the third-party software products you are integrating with HDP are certified to work with the HDP intermediate bits.
Ambari and the stack managed by Ambari can be upgraded independently. Use this document to upgrade Ambari and HDP.
